Update to KA re-removing auto suggestion

This is a follow up post to this post. Read it first.

Pamela replied to my comment and said that she liked the idea of including auto suggestion as an option, but she was focused on cleaning up the underlying source of repository first. I definitely agree with her decision. I mentioned the “complicated history” of this issue, and I agree it would probably be simpler to rebuild this part of the live editor with modern components. But I guess I’m still very skeptical that anyone will go back and re-add these features that got lost over the years after the immediate rebasing is complete.

I also pointed out to Pamela how KA could remove Ace’s language tools, as they were only used by auto suggestion. I’m shooting myself in the foot here a bit, because it means that if I want to turn on auto suggestion again, I have to reload these language tools. Anyways, here’s the quick fix to turn auto suggestion on. It still doesn’t redo KA’s improvements to auto suggestion, so it doesn’t suggest ellipse or rect until you’ve used them once in your project. I’d like to be able to support those things again, but I don’t see a way to do it without manually loading the hundreds of lines of code that Pamela removed.

var scriptEl = document.createElement("script");
scriptEl.setAttribute("src", "https://cdn.jsdelivr.net/gh/ajaxorg/ace-builds@1.1.4/src-min-noconflict/ext-language_tools.js");
scriptEl.addEventListener("load", function () {
    ace.require("ace/ext/language_tools");
    ace.edit(document.querySelector("scratchpad-ace-editor")).setOption("enableLiveAutocompletion", true);
});
document.head.appendChild(scriptEl);
